Abstract

The gastric and intestinal bacterial floras of healthy piglets of five large white sows were examined before and after early weaning at 14, 21 or 28 days of age. Piglets of three litters were farrowed and reared in climatic chambers, while those of the remaining two litters on the were reared under conventional conditions. The pH and bacterial flora did not differ significantly in the cardiac and pyloric parts of the stomach. Conditions in the duodenum had a marked inhibitory effect on all examined bacterial components except coliforms, suppressing especially the clostridial growth. Bacterial counts rose gradually in the more posterior segments of the small intestine, and in the terminal portion of the ileum they approximated the values characteristic of the large intestine. Bacteriologic status and pH were essentially similar along the cecum, mesocolon and rectum. Inhibition of coliform growth by a low gastric pH (1.5-2.5) was clearly demonstrable in a few cases, but the usual pH range (2.5-4.5) had no noticeable effect. No pH related alterations of bacterial flora could be detected in the more posterior segments. The fullness of the jejunum was found to be positively correlated with the bacterial population: the greater the amount of chyme, the higher the number of bacteria, and above all of coliforms. Weaning in itself did not notably affect the bacterial flora of either stomach or intestines. Environmental conditions, however, had a demonstrable influence on the bacteriologic status of all examined segments. Farm reared piglets carried a significantly larger coliform population in both small and large intestine than their age mates reared in climatic chambers and exhibited an irregular lactobacillus streptococcus coliform ratio already during lactation.
